£260.08
The Wöhner 33504 is a robust three-pole NH fuse switch-disconnector engineered for safe switching, circuit isolation and overcurrent protection in industrial low-voltage power distribution systems. As part of the proven QUADRON® 60Classic Speed range, it combines dependable performance with external door operation, making it ideal for machine builders, panel manufacturers and industrial electrical installations.
The unit features an operator-independent snap-action switching mechanism with double-breaking main contacts, ensuring consistent switching performance regardless of handle operation. Designed for use with a door coupling rotary handle, it allows safe switching from outside the enclosure while maintaining high levels of operator safety. The double-breaking contact system also enables safe, tool-free fuse replacement and provides a visible isolation gap when the fuse carrier is removed.
Designed for NH size 00 fuse links, the Wöhner 33504 has a 125 A rated current and supports operation up to 690 V AC. Its top box-terminal connection simplifies wiring while integrating directly with Wöhner 60Classic busbar systems, making it suitable for industrial switchboards, motor control centres and OEM equipment.
The Wöhner 33504 combines fused overcurrent protection, reliable switching and secure electrical isolation within a compact device. Its spring-controlled switching mechanism delivers consistent performance, while the double-breaking contact arrangement enhances safety during fuse replacement and maintenance.
When used with the appropriate Wöhner red/yellow door coupling rotary handle, the switch-disconnector can serve as a main isolator or Emergency OFF switch in accordance with relevant industrial standards, making it an excellent choice for modern switchgear assemblies.
